Table 1.

Compares the percentage reduction in colony forming unit count among four groups

Group	Mean	SD	P
2% CHX	77.06	2.12	<0.001*
A. indica	77.58	1.45
Triphala	79.80	1.81
Calcium hydroxide	53.70	1.70

*A significant difference at P<0.05. Percentage reduction in CFU count was highest in the triphala group followed by A. indica and 2% CHX group. Percentage reduction in CFU count was least in the calcium hydroxide group. One-way ANOVA test. SD: Standard deviation, CFU: Colony forming unit, A. indica: Azadirachta indica, CHX: Chlorhexidine
